The move is a part of the company’s ZAR20bn ($1.8bn) investment at the project for two large vertical shafts and a decline shaft, which will be installed at a depth of 1km in the pit.
DBCM CEO Phillip Barton was quoted by Mining Weekly Online that the mine would feature similar technology as that of its previously-owned Finsch diamond mine in the Northern Cape.
"We’re certainly taking the learnings that we had out of Finsch mine forward and incorporating them into the design of the Venetia underground mine," Barton said.
The company plans to employ other mining techniques to produce 5.9 million tons of ore each year and treat 130 million tons of ore.
The Venetia mine is on track to commence production of first diamonds in 2021, and boost its production in 2024, Barton added.
